The Role of Ophthalmology in Tele-Stroke Consults for Triaging Acute Vision Loss.

Advances in telemedicine have allowed physicians to provide care in areas that were previously geographically or practically inaccessible. Roughly 70% of all US hospital have less than 200 bed capacity and nearly 50% have fewer than 100 beds. These smaller hospitals often do not have specialists available for bedside patient care, making them potential beneficiaries of telemedicine medical specialty services. In 2005, the American Stroke Association proposed implementing telemedicine services in effort to increase access to acute stroke care in neurologically underserved areas such as small hospitals. Tele-stroke services have since become established across the country and are now utilized by approximately 30% of US hospitals. By reducing the time between presentation and evaluation by a stroke specialist, tele-stroke programs have successfully increased patient access to life-saving treatment with tissue-plasminogen activator (t-PA) treatments. This change has been especially profound remote and underserved community hospitals. However in the evaluation of acute vision loss, an area where ophthalmology and stroke care overlap, increased reliance on tele-stroke services has contributed to some unique challenges. Acute vision has a complex differential and is commonly a result of conditions other than stroke. When tele-stroke services are engaged for the evaluation of acute vision loss, the neurologist is asked to make medical decisions without complete information about the eye. This situation can expose patients to costly or inappropriate testing, unnecessary hospitalizations, or lead to delayed diagnosis and treatment of non-neurologic conditions of the eye. The goal of this paper is to provide an overview of the overlap between stroke and vision loss, highlight the challenges inherent in using tele-stroke in evaluating acute vision loss and to offer our comments on how increased communication between emergency medicine, ophthalmology, and neurology services can ensure that patients with vision loss receive the highest standard of care in all hospitals.
